Poop comes in all shades, often a result of what we eat and chemical changes due to bile as our food gets digested.
Normal poop color is brown though sometimes if we eat green leafy vegetables it could be on the greener side. A sudden color change could be indicative of a health problem.
Know what your poop color indicates and when it could mean trouble:
Green: Green colored stool could be due to iron supplements, green leafy vegetables, however, it could also mean that the food is moving too quickly through the large intestine as a result of which bile doesn’t have the time to break down the food completely.
White, Clay or Grey: Whitish, grey or clay-colored stools indicate lack of bile and often indicate a problem with gallbladder or liver. The problems could be as varied as liver cirrhosis needing a liver transplant or liver failure due to hepatitis A, Hep B or Hep C.
Yellow: Unless, you are having too many yellow colored liquids, yellow stools indicates, excess fat or poor fat absorption.
Poor fat absorption could be due to blocked bile ducts, a problem with the pancreas, and may indicate lack of enzymes for food digestion or may even point towards chronic pancreatitis, celiac disease.
Red: Unless you have been eating beets, carrots, tomatoes, cranberries, food with red coloring, bright red colored stool may indicate bleeding due to hemorrhoids, anal fissure, and even colon cancer or cancer of the rectum or even bowel cancer.
Black: Black colored stools, may indicate bleeding from the intestines, stomach which may even indicate stomach cancer and need an immediate follow-up call with a doctor.
A diet rich in blueberries or black licorice, iron supplements, bismuth subsalicylate could be other exceptions.

Robotics or computer assisted surgeries are helping patients with advanced cancer care. Robotic surgery effectively means’ robotic systems designed specifically to assist surgeons perform, complex surgical procedures with precision, control and dexterity.
These are often difficult to reach cancerous tumours, which the surgeons are able to view with increased vision and hence excise with precious thanks to video assisted robotic systems.
In general, the surgeon uses the robotic systems, arms to perform the surgery instead of his own hands. Most good systems come equipped with cameras and 3D imaging to enable surgeons to view deeper locations inside the body and reach the diseased tissue with greater range of motion and precision.
Cyberknife, Gamma Knife, Novalis, Da Vinci are various forms of robotics systems available to assist surgeons.
